The patterned Langmuir–Blodgett (pLB) technique has been used to generate micrometer‐sized structures of Pt@Fe 2 O 3 core–shell nanoparticles. The composition of these core–shell nanoparticles has been further converted in situ into face‐centered tetragonal phase FePt, one of the best candidates for ultra‐high‐density magnetic‐storage media without loss of the pattern (see Figure).
